With the progress of the war raw materials began to be scarce and in particular gold for nibs, as the majority of European companies [[OMAS]] had to resort to some steel alloy, that the company renamed ''[[Permanio]]'', that was declared to be better even than gold. In fact just this alloy proved to be one of the most susceptible to corrosion, so that today ''[[Permanio]]'' nibs are rare and have a much higher value of their analogues in gold.

After the war production resumed with new ogival pens and the transition to [[piston filler]]. In [[1946]] the [[Omas Extra|Extra]] line was completely restyled, the wheel clip was maintained but  were used three rings on the cap. Also the [[piston filler]] was adopted and  a transparent section for viewing ink level was introduced. Three sizes were maintained: small, medium and large, identified respectively with the numbers [[Omas 55x|555]], [[Omas 55x|556]] and [[Omas 55x|557]].
